Installed on a slightly modified 2001 Audi A6 Quattro 4.2L V8 A few weeks Before: Dyno'd in at 331ps@6200rpm and 304ft-lbs@3000rpm A few days After: Dyno'd in at 342ps@6200rpm and 317ft.lbs@3000rpm That's around 3.5% increase. A tiny decrease in fuel consumption, noticeably increased throttle response. Overall alot perkyer performance and responsivity. Worth it imo. Also worth noting that the old plugs were extremely nasty, and were installed only god knows when. Im only assuming that if I had swapped out decent plugs for these the increase would be smaller.
